Benefits of technology

The composition enables the precise implementation of fine patterns with improved uniformity and reduced process time, minimizing blanket deformation and environmental impact, while reducing costs associated with traditional methods.

Problems solved by technology

However, the photolithography method causes an increase in process costs due to costs of photosensitive materials, which are not included in a final product and are developed and removed, and an etchant and disposal costs of the photosensitive materials and the etchant.
Further, there is a problem of environmental pollution caused by disposal of the materials.
In addition, the method has many processes and is complicated, and thus much time and costs are required.
The screen printing method and the inkjet method have limitations in implementing a fine pattern having a size of several ten micrometers.
